RE: What safety precautions to keep in mind?
You got most of the basics down. Here's my current pet peeve. Since I fly at a field where nitro/gas planes are the norm, I see a lot of pilots trying out electrics for the first time. So most, after landing will shut the engine down and retract the TX antenna and carry this practise over to electrics. At least one electric has gone flying on its own due to this practise!
